What “certh” means

Wikipedia

The Cirth is a semi‑artificial script, based on real‑life runic alphabets, one of several scripts invented by J. R. R. Tolkien for the constructed languages he devised and used in his works. Cirth is written with a capital letter when referring to the writing system; the letters themselves can be called cirth.

#certh across platforms

every network with a public tag surface

Follow #certh straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
